thank you for the post
I have a problem, when i wrote “” sudo ./usbip attach -r 192.168.1.13 -b 1-1.3 “”
the following error appears:
libusbip: error: udev_device_get_sysattr_value failed
usbip: error: open vhci_driver
usbip: error: query

even after wrote the following “” sudo modprobe vhci-hcd “”
the same error still appears.

THANK YOU…. Been pulling my hair out all day messing with this on a Rock Pi 4B. This finally got it working. Anyone else who finds this for a Rock Pi–the kernel source files are here: https://github.com/radxa/kernel
